How much of a difference is this new solder for the average solderer?  I'm not exactly soldering to microchip legs over here.  Will a novice like me even notice a difference with the tin stuff?

Link, please.  Looking up the part number on the Kester website leads me to nothing relevant.  This is the only match I see - and that clearly isn't for solder.

Plenty different. You'll be working with what essentially is a hunk of wire instead of solder. This new stuff requires considerably more heat which will lift foil traces on many circuit boards. Flowability is much different. "Whiskers" will be prevelant which will cause short circuits.

In other words you'll now be doing wire feed welding!

the underground market is already alive and well

some of the equipment I work with has to work at temperatures between -10 and well over +100 deg C while suffering quite heavy vibration, I found out the hard way about the dry joints with lead free solder on cold winter mornings. we started to find that on cold mornings our winches were breaking the soldered connections on the windings when we started operating them while our older winches which were soldered with lead based carried on working regardless, it took a while to work out the cause, It would appear that lead-free is a little more brittle at low temps

That makes sense. It's been posited that Napoleon's 1812 campaign into Russia failed due to the tin buttons on the soldiers clothing disintegrating during the intense winter cold.
